Produção e Qualidade Física dos Frutos do Abacaxi sob Diferentes Lâminas e Frequências de Irrigação

The objective of this study was to evaluate the performance of pineapple cultivar Smooth Cayenne as the physical production and the quality of the fruit when subjected to different frequencies of water dpeth and soil water in Triângulo Mineiro - Uberaba-MG. The experimental area soil is Oxisol, clay loam sandy and soft undulating local relief. A randomized block design in a factorial 4 x 2 with four levels of soil water depth (50%, 75%, 100% and 125%) of crop evapotranspiration (ETc) and two irrigation frequencies (1 day and 3 days = F1 = F2) and four replications was utilized. The crop productivity, number of seedlings, mean weight, diameter, and hardness of the fruit, plus water use efficiency were evaluated. Productivity was not significantly affected by the water depth and by the frequency of water applied; however the fruit shell resistance, the efficiency of water use, and ratoon seedlings were significantly influenced by irrigation, the water depth of 50% of the crop evapotranspiration (ETC) provided greater efficiency of water use for the production of pineapple fruit.

Crescimento da grama bermudas sob diferentes lâminas de irrigação

The objective of the present study was to analyze the most appropriate water depth for maintaining a good quality of Bermudas Grass (Cynodon dactylon) for soccer fields while saving water and electrical resources. Four treatments were used: T1 - irrigated with a water depth of 50% of evapotranspiration (ETo), T2 - irrigated with a water depth of 75% of ETo, T3 - irrigated with a water depth of 100% of ETo and T4 - irrigated with a water depth of 150% of ETo, all treatments were irrigated daily. The reference ETo was obtained by the Penman-Monteith method. The study was conducted in an experimental area of the Instituto Federal de Educação, Ciência e Tecnologia do Triângulo Mineiro - Campus Uberaba, Uberaba, Minas Gerais, Brazil, from June to September 2010 and from January to March 2011. Three evaluations of the variables were performed during the experimental period. The samples were obtained with the help of a cylindrical extractor with 10 cm in diameter and 30 cm in height. In each sample height and dry organic matter (leaf, root and organic material) were analyzed. The experimental design was randomized block with four treatments in five blocks. No significant differences were observed for dry matter and height (roots and organic material). The best results were those for T4 which obtained the greatest height.
